šŸ‘Øā€šŸ«Profile Summary

I am an analytical environmental chemist with expertise in applying a diverse suite of analytical techniques to investigate environmental questions. My research focuses on studying the composition and environmental fate of pyrogenic (fire-derived) organic matter (pyOM) and soil/aquatic natural organic matter (NOM). I employ ultrahigh resolution mass spectrometry (FT-ICR-MS), various spectroscopies (e.g., fluorescence, NMR), liquid- and gas-chromatographic techniques, as well as stable isotopes to develop novel analytical methods.
